    gdb/doc: Update 'frame' command documentation.
    
    The documentation for the 'frame' command has gotten a little out of
    date, it still mentions architecturally specific details that are no
    longer relevant.
    
    This commit removes the old details that no longer apply, and tries to
    expand the existing text a little to make the usage clearer for some
    cases.
    
    gdb/doc/ChangeLog:
    
    	* gdb.texinfo (Selection): Update documentation for 'frame'
    	command.
